First of all, sorry for my unclear writing in english.In my -01 omega z22xe classic has a function that when example in winter you leave the car on the parkingarea and after you've turned off the engine and taken the key off from ignition, you can push the auto button on climatecontrolpanel and it should start the heaterfan and the electric waterpump thats located under the coolingtank(or what ever it's in english:D) but in mine's the socalled pauseheater only starts the heaterfan and the climatecontrolpanel but not the waterpump because it only gives 0.3 voltage for the connection of the waterpump.Did anyone understand what i said and ment?It seems that here in finland allmost every B2 model omega owner has issues with this same function and i haven't found a solution yet from members of Opel Club Finland or from other omega owners.Would you guys here have any suggestions or solutions for this?

I feel your pain.In finnish forums the guys who work on opel service are talking about something about that the voltage from climatecontrolpanel is too low to close the relay that starts the pump at the same time with the heaterfan but i really would like it to work like it is supposed to even if it means some wiringjob behind the controlpanel to get enough voltage to the pump.

Radiatorfan and the climate works fine, allthou the climatesystem has a very tiny leak in some place that isn't easily detected because the system holds it's pressure and liquids in only about a half a summer.

Right, checked diagrams, pump is driven directly from ECU, so if it ain't getting the voltage its either wiring, or the ECU isn't bringing pin 19 to 12v. If latter, either faulty ECU, or config programming on it/

I have something similar. When "Auto" pressed the fan starts for perhaps one minute or two and then fades away. I did not check the Voltage got to that pump but I will do that soon. I have also a laptop with possibility to check many things. Does anyone remember is there anything to just "activate" in Climate Control Section or does it need a real TECH2?

The pump under the expansion tank, is part of the winter pack, and operates, when the ignition is off, and I think re-circ is pressed,, it opereates for about 5 mins in the cabin warm, too stop passenger getting cold, when you take keys out engine off.

The problem is that is not what actually happens all the time - sometime it needs a chat with Tech2 to enable that feature
